Hybrid Tea rose plant named ‘Ruimx19’

ABSTRACT

A new and distinct Hybrid Tea rose plant having attractive purple red flowers.

Classification: The present invention relates to a new Rosa hybrida L. plant.

Varietal denomination: The new plant has the varietal denomination ‘Ruimx19’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea rose class, which was discovered as a natural branch mutation in a controlled planting of ‘Ruidusty’, unpatented.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are flowers of attractive purple red color.

Asexual reproduction by propagation by grafting of the new variety as performed in De Kwakel, The Netherlands shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

COMPARISON WITH PARENTS

Among other respects, the new variety differs from its parent in flower color, inasmuch as the parent has flowers ranging from orange red to yellow brown pink with cream yellow and purple red spots, whereas the new variety has flowers that are purple red.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows a typical specimen of the new variety depicted in color as nearly true as is reasonably possible to make the same in a color illustration of this character. In the illustration are shown new foliage 1; leaflets 2, 3 and 4; a stem with thorns 5; flowers in different stages of development 6, 7, 8 and 9; and reproductive organs 10, 11 and 12.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary with light availability, environmental and cultural conditions.

The following observations are made of 9-month old plants grown in a greenhouse in De Kwakel, The Netherlands during January from a grafted cutting.
